1035206102 lavf/dashdec: Add webm to the list of allowed extensions. 
This is in coherence with dashenc, which can now generate segments with
webm file name extension by default. Dashdec should be able to handle
such streams by default as well.

4e3e8980b5 dashdec: Fix segfault on decoding segment timeline 
If first_seq_no is not within the bounds of timelines then a segfault
will occur.
This patch removes the use of first_seq_no within the timelines array
It also adds first_seq_no to the value returned by calc_next_seg_no_from_timelines
(which allows for different values of 'startNumber')

1f48c5c067 dashdec: Only free url string if being reused 
If no representation bandwidth value is set, the url value returned
by get_content_url is corrupt (as it has been freed).
This change ensures the url string is not freed unless it is about
to be reused

 1 removed the unneeded 'if' statement (as pointed out by Michael Niedermayer

66e551eafb dashdec: Expose bandwidth and representation ID as metadata 
The primary goal was making it viable to play YouTube/Vimeo/... videos
using the native demuxer, since mpv currently uses a workaround in form
of Edit Decision Lists (EDL).

Implemented features:

1 Exposing id / bitrate as stream metadata (similar to the HLS demuxer)
2 Support for multiple video and audio streams
3 A few minor parts of the specification that are in use at YouTube
